I located a restaurght. Where a garbage bin in back an label old cooking or fryer oil, think about ask if have, pretty sure they well, wondering what can do old fryer oil ?

Bait?

lot of places buying it now for bio diesel.

another waste item turned commodity.

Don’t know if I should mention this but I heat my garage with all kinds of used oil...pick it up from the transfer station, kfc or wherever. I filter it, blend it, keep it warm and don’t get no smoke out the pipe! Most of the time it smells like french fries, sometimes it smells like the neighbors idling truck..
I burn it in a 1930’s estate heatrola waste oil burner.

The primary uses around here are fuel and bear bait. Black bears love the stuff.
It can be burned in a waste oil burner like Wylee said, or it can be filtered, sometimes diluted and burned in diesel engines. Lots of older diesels (pre-common rail injection) burn WVO (Waste Veggie Oil) quite well. There's loads of info about it on internet forums and YouTube.

They are probably selling it.

Back when I trapped coon I would get all the old fryer oil and grill scrapings from every restaurant In the area. I would furnish the 5 gallon buckets and they would fill them.
I would set them out In the sun and let them heat up the fine oil would rise to the top and the heavier meat particles and the other heavy grease would sink to the bottom. I would just pour off the lite oil leaving the heavy stuff behind. The lite oil would be used as a trailing scent and the heavy stuff would be used as a bait. Makes for some great slap and go bait . I also used It In dirt holes for canines.
Get It If you can.

Good stuff!!!

Most restaurants will give it to you free. They now have to pay for disposal so you taking it helps them. Just don’t make a mess collecting it from them.

Go out on your line. Dig a hole 4- inches wide and 18-inches deep. (Drill with 4-inch auger). Pour in the fryer oil. Take a picture of the filled hole. Go home. Come back in a week. That 4-inch wife hole will now look like a small bomb went off. There will be tracks and scat everywhere! It helps to hide a trail cam close by so you can catch the action. I’m told fish fry oil is best. Chicken fry oil is super also. Used fryer oil rocks!!

Someone at convention say had some old wood an soak it in it an lay by creek bank, I thought. Ahead season, I have to see if could get just 5 gallon bucket, use a dish soap squirt bottle to squirt out. Use heavier stuff for bait, wonder if stinks ?

I used to use cooking oil mixed with shellfish oil as a trailing sent for coon

I haven't found an animal that doesn't like it yet. Best to check with the restaurant some of them sell it. They probably wouldn't like you taking it. Some of them just have it hauled off by a company and pay for it. Those would be your best bet.

Around here in any sort of warm weather its amazing at turning a set into a giant fire ant bed.

I used it the same way for coon as a trailing scent to entice them to where I had a trap like a pocket set, dog-proof, etc waiting.
